Multi-Stage Encoding Scheme for Multiple Audio Objects Using Compressed Sensing
Object-based audio techniques have become common since they provide the flexibility for personalized rendering. In this paper a multi-stage encoding scheme for multiple audio objects is proposed. The scheme is based on intra-object sparsity. In the encoding phase the dominant Time Frequency (TF) instants of all active object signals are extracted and divided into several stages to form the mult...
متن کاملFrames for compressed sensing using coherence
We give some new results on sparse signal recovery in the presence of noise, for weighted spaces. Traditionally, were used dictionaries that have the norm equal to 1, but, for random dictionaries this condition is rarely satised. Moreover, we give better estimations then the ones given recently by Cai, Wang and Xu.
متن کاملEfficient Encoding of a Sinusoidally-Modelled Audio Signal Using Compressed Sensing
In this paper, the compressed sensing (CS) methodology is applied to the harmonic part of sinusoidallymodelled audio signals. As this part of the model is sparse by definition in the frequency domain, we investigate whether CS can be used for encoding this signal at low bitrates, instead of encoding the sinusoidal parameters (amplitude, frequency, phase) as current state-of-the-art methods do. ...

متن کاملToeplitz Random Encoding for Reduced Acquisition Using Compressed Sensing
INTRODUCTION Considerable attention has been paid to compressed sensing (CS) in the MRI community recently (1,2). CS theory allows exact recovery of a sparse signal from a highly incomplete set of samples (3,4), and thus has the potential for significant reduction in MRI scan time. While most existing work has focused on Fourier encoding, non-Fourier encoding has shown some promise (5,6). In th...
